摘要
本文分别采用弹性理论公式、ANSYS软件的梁单元和壳单元计算单跨简支受弯铝合金E形截面薄壁构件在不同载荷形式、不同载荷作用点位置以及不同跨距时的弹性整体失稳临界弯矩。对计算结果的分析表明,使用壳单元计算E形截面薄壁构件受弯整体稳定临界弯矩时,能达到较好的精度。
This paper uses elastic theory formula,beam element and shell element of ANSYS software to calculate the elastic critical moment of global buckling for aluminum bending thin-walled member with E-section which is simply-supported and loaded different kind and different position of loads in different spans.The conclusion that the shell element is more accurate when calculating the critical moment of global buckling for aluminum bending thin-walled member with asymmetrical section(such as E-section in this paper) is proved.
